Q. Which of the following conditions results in the highest density of sea water?
Answer: Depth increases and salinity increases
Notes: The density of surface seawater ranges from about 1020 to 1029 kg/m³.It depends on the temperature and salinity. As the depth increases the salinity also increases. At a temperature of 25 °C, salinity of 35 g/kg and 1 atm pressure, the density of seawater is 1023.6 kg/m³. Deep in the ocean, under high pressure, seawater can reach a density of 1050 kg/m³ or higher.
